PLAYDV

NAME

SYNOPSIS

DESCRIPTION

playdv reads in DV-encoded video data from file and displays
it on screen.

-v, --version

show playdv version number.

--disable-audio

skip audio decoding.

--disable-video

skip video decoding.

-n, --num-frames=count

stop playing after count frames.

--dump-frames=pattern

save a PPM image of each frame to an individual file. pattern determines
the file names and may be given in printf-style taking one numeric
argument that gets replaced with the current frame number. Like
capture%05d.ppm for files capture00001.ppm, capture00002.ppm, etc.
Use - to stream the frames to stdout.

sets the video standard of the incoming DV data: 0=autoselect [default],
1=525/60 4:1:1 (NTSC), 2=625/50 4:2:0 (PAL,IEC 61834 DV),
3=625/50 4:1:1 (PAL,SMPTE 314M DV). Autoselect usually works fine. Only
use this option if you know what you are doing.

Video Decode Options

-q, --quality=(1|2|3)

quality level of desired video decoding. The process of decoding DV data
is split into several steps. Each additional step enhances output quality,
but of course also slows down decoding. If your machine is too slow to
keep up an interactive frame rate, you might want to decrease this number:
1=DC and no ACs, 2=DC and single-pass for ACs, 3=DC and multi-pass
for ACs [default].

-m, --monochrome

skip decoding of color blocks. Another way to speed up the decoding process.
